`V Application filed September 11, 1922. lSerial N'o. 587,569.

Y To'aZZ whom t may concern: Be it known that I, PEROY OoTAviUs Rowy LiiNDs, a .subject of the King of England,

residing at 27 Abercromby Square, Liverpool, in the county of Lancaster, England, have invented new and. useful Improvements in and Connected with Motor Vehicle or Other Power-Transmission Mechanism, of which the following is a specification.

This invention relates toV mechanism whereby poweris transmitted through friction disks or wheels, and thev frictional surface of one of which disksY Or wheels is of india-rubber or its compounds. The invention is particularly applicable to the power the above purpose, and a splashing effect of water or liquid on Vthe surface may be used. Y

'lVith regard to the driving and driven disks, the driving disk may vbe provided with a rubber face suitably secured in a metal disk, the rubber being of the type used in solid tires and the driven disk is preferably of metal. I will further describe my invention with the aid of the accompanying sheet of explanatory drawings, whichV illustrates its application-by way of example only-to thev driving mechanism of a self-propelled vehicle. Y A

In said drawings vFigure 1 is av longitudinal 'section of the variable speed lpower transmission mechanism and a liquid retaining casing;

- F ig, 2 isr an Velevation viewed at right angles to Fig. 1, and

Fig. 3 is a plan.

l represents a horizontally disposed `disk secured to the lower end of an engine crank shaft 2, said shaft 2 extending through a cover 3. To saidhorizontal disk l there is detachably'secured by means of bolts 4: la facing or mat ln of india-rubber, preferably of the quality commonly Vused inthe manufacture of solid rubber tires, and

which may berreinforced'with canvas, or the; like. Slidably disposed'upon a vshaft oi'spindle 5, 5a (the end 5a whereof is connected to the Cardan shaft ofthe vehicle) is a driven disk 6 -which may be conveniently constructed of a suitable metal, sayan aluminum alloy. Attached by means of thel bolts 7 to said cover 3 is aliquid-retaining casing 8 which, together with said cover 3, encloses said Vdriving and driven members 1,'1, and 6 of the transmission mechanism.

VSaid casing 8 also supports said shaftJK 5, 5ar

which is carried in eccentrically disposed ball bearings 9, 9. Y l Said driving'disk 1, l, is rotated by means of shaft 2 and, in turn, rotates said driven disk 6 which is vforced, into cont-act with it by means `of the tension springs 10 acting through levers Il and eccentric blocks 12. y

Said liquid-retaining casing '8 is provided with sufficient liquid 13, preferably water, rto enable the driven Vdisk 6 to dip therein, as shown in Figs. l and 2, so that the co-acting surfaces of the driving and' driven disks are automatically wetted.

My object in subjecting or treating whilst in r'motion the co-actingvv frictional surfaces ofV the disks or wheels, when one of the same is of india-rubber or its compounds, 1

to or with 'a suitable fluid, preferably water,

is toincrease'the useful life of the rubber and to maintain a substantially constant frictional value 'between the said cosacting frietional surfaces.

That I claim is:-

1. A power transmission .mechanism co1nv called for in'claim l, wherein the friction.

disks are disposed at a'right angle to. each other with the rubber surfaced diskV above the body of liquid.

3. A power transmission mechanism conipiisinga casing. friction disks. rotatable in said Y,ca-singl with one of said' disks provided with a surface of india rubber or its coinconstant frictional value between said disks. pounds and the other disk disposed at a In testimony whereof I atix iny signature right angie to the rubber surfaced disk, and in the presence of two Witnesses.

abody of liquid located in proximity to PERCY OCTAVIUS ROVLANDS. said disks and adapted to be supplied to Witnesses:

said disk to increase the useful life of the JOHN HINDLEY WALKER2 rubber surface and maintain a substantially IsoBnL F. V. HINDLEY WALKER.
